No presence information in Outlook (Skype for Business)

Got an issue after installing the Mitel MiCollab software. Microsoft Outlook did not display the status of Lync/Skype anymore. Also in my Outlook client the information from GAL (Global Address List) was not visable anymore when hovering over a name.

Some other issues i found out:

  • The Microsoft SharePoint client/web does not display presence information.
  • Other Microsoft Office applications that support presence features do not display presence information

The Solution

This behavior may occur if the value of the DefaultIMApp registry entry in the following registry key is incorrect:

First, look at this location in the registry…

[HKEY_CURRENT_USER\Software\IM Providers] 

It should show this value:

“DefaultIMApp”=”Lync”

If there is any other value, change it back to “Lync”, in this case the MiCollab software is changing this value to “Micollab”.

Now restart Outlook and see if your presence indicators are back.

Note: The DefaultIMApp registry entry specifies which IM application provides IM and presence information in Office applications.

Execution of Scripts is Disabled on this System

When you try to run a powershell script on Windows, you may receive the following error stating that the execution policy on your computer does not allow you to run the script.

To fix this error, you must change the PowerShell execution policy for this computer.  These instructions will explain how to allow “Unrestricted” access to running scripts on your computer.

  1. To set the execution policy to unrestricted, enter the following command (PowerShell must be run as an Administrator):
    1. Set-ExecutionPolicy Unrestricted
  2. You will receive a warning indicating that you are trying to change the execution policy and the risk that is associated with the change.  Enter ‘Y’ and press enter.
  3. Your execution policy is now changed.  You can verify this by executing the command “Get-ExecutionPolicy”.  You can now try to run your script again and you should not receive any errors.
